A Denver District Court judge Friday dismissed all charges against Franklin Sain, a Colorado Springs man accused of sending state Rep. Rhonda Fields a series of profanity-laced e-mails, putting an end to a case that raised questions about the subtle differences between political and criminal speech.

Prosecutors asked Judge William Robbins to dismiss the case at the request of Fields, D-Aurora, who they said did not want to proceed because her safety concerns were addressed through a permanent protection order she obtained this week that bars Sain from contacting her. Another provision requires Sain, 42, to undergo mental health treatment, Chief Deputy District Attorney Henry Cooper said, though that condition is not listed on the protection order.

Sain, a former IT executive, lost his job with SofTech Solutions in February when the district attorney’s office charged him with harassment involving ethnic intimidation and attempting to influence a public servant, a felony. He told Denver police he sent Fields six e-mails filled with profanity and epithets and left similar voice mails between Feb. 13 and 15, during her efforts to tighten state gun laws.

Police also believe he sent Fields an unsigned, threatening letter that said: “I keep my 30 Round Magazines There Will Be Blood! I’m Coming For You!” which his attorney, Siddhartha Rathod, routinely denied.

Rathod maintained that, while offensive, his client’s e-mails were protected free speech and not true threats. In June, Fields sought a permanent protection order against Sain that would have barred him from her home and her workplace, the state Capitol. The agreed-upon order issued Tuesday requires Sain to stay 100 yards away from Fields but allows him to visit the Capitol.

“It still was a sound case in terms of provability,” Cooper said after the short court appearance. “Once a victim says they don’t want to prosecute … that’s pretty much the end.”

Deputy District Attorney Courtney Johnston told Robbins that Fields, whose son was shot and killed in 2005 before he was able to testify against a gang member, did not want to endure the criminal justice system again.

“I am very pleased with the outcome of the Civil Protection Order trial. My concerns have been addressed and it’s time to move on,” Fields wrote on her Twitter account Friday.

Attorney Craig Silverman, who represented her in the civil matter, reiterated her sentiments but did not comment further.

Sain did not comment after the hearing and Rathod said only, “The result speaks for itself, and we are satisfied with the result.”

The owners of Boulder’s Sterling University Peaks apartments, who this summer were cited for illegally subdividing 92 bedrooms in the complex, have reached an agreement to settle the case for $410,000, the city announced Thursday.
